WILLIAM SIMS, OF STAYTON, OREGON.

WATER-WHEEL.

. SPECIFICATION forming part of Letters Patent No. 227,065, dated April2'7, 1880.

Application filed January 20, 1880.

To all whom it may concern:

Be it known that I, WILLIAM SIMs, of Stayton, in the county of Marionand State of Oregon, have invented a new and useful Improvement inSectional Turbine \Vater-Wheels, of which the following is aspecification.

Figure 1 is a plan. view of my improvement. Fig. 2 is a perspective viewof two sections of the wheel. Fig. 3 is a sectional elevation takenthrough the line a m, Fig. 2.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish sectional turbinewater-wheels so constructed that the sections may be easily put togetherand will be held firmly in place.

The invention consists in constructing the sections with inner rimshaving their ends rabbeted, inclined buckets, and outer rims, madethicker than the inner rims, to give the inclined buckets a slighttwist, as will be hereinafter fully described. The wheel is formed often (more or less) sections, and each section consistsof an inner rim,A, an inclined plate or bucket, B, and an outer rim, 0.

The inner rim, A, is designed to fit into a recess in a wooden shaft, orbetween flanges upon an iron shaft, and has ribs or tenons D upon themiddle part of its inner or concave surface, to fit into grooves ormortises in the shaft. The ends of the sections A are rabbeted upon thealternate sides, and one of the said rabbeted ends projects, as shown inFig. 2, so that the adjacent ends of the rim-sections A may be halved toeach other.

The bucket B is made in the form of an inclined plane, as shown in Figs.2 and 3. The outer rim, 0, is made in the form of a section of a hoop orband, as shown in Figs. 2 and 3, and is thicker than the inner rim, A,as shown in Fig. 3. The inner or concaved edge of the inclined plane orbucket B extends from the upper side of the convex edge of the innerrim, A, to the lower side of the said edge. The outer or convexed edgeof the bucket B extends from the upper edge of the outer rim, 0, to itslower edge, as shown in Fig. 2. The greater thickness of the outer rim,0, gives a twist or spiral shape to the bucket B, which tends toequalize the force of the water during the action of the wheel.

Each section A B O is castin one piece, and the sections are boundtogether by a tire placed upon the outer rims, O, as indicatedin dottedlines in Fig. 1.

The wheel may be made with any desired number of sections. The sectionshown in the drawings is designed for a ten-section wheel.

By varying the number of sections and the relative thickness of the rimsA O the pitch or inclination of the bucket B will be varied as thedesired power of the wheel and the fall of the water may require. Withthis construction the wheels can be made at less cost than wheelsconstructed in the usual way, and any damage or breakage can be moreeasily and cheaply repaired.

In the case of small wheels with a thin rim the ends of the adjacentsections may be made square, and need not be halved to each other, asthat construction would make them too weak.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A turbine water-wheel made in sections,substantially as herein shown and described, each section consisting ofan inner rim, A, an inclined bucket, B, and an outer rim, 0, as setforth.

2. In sectional turbine water-wheels, the section A B O, constructedsubstantially as herein shown and described, consisting of an inner rim,A, having its ends rabbeted, an inclined bucket, B, and an outer rim, 0,made thicker than the inner rim, A, as set forth.

YVILLIAM SIMS.
